One flew to the papaya tree
There were two of them, White-cheeked Barbets (Scientific name: Megalaima viridis), one was singing and the other presumably, listening. But when they heard me and Luci climb the stairs, they hurriedly flew away, one to the mango tree, where it impersonated a mango leaf and was hence harder to spot, and the other to the papaya tree, to sing some more in full view.
